Description

[Detailed description of the invention] The present invention is a stand-alone device for the lid of a floor opening, and more specifically, a lid plate that opens and closes an opening formed on the floor surface, such as the opening of an under-floor storage compartment, which stands by itself in an open state. This invention relates to a lid self-supporting device.

Conventionally, devices have been provided that allow the lid to stand on its own in an open state in underfloor storage cabinets, etc. In this type of lid self-supporting device, a pair of arms are provided on both sides of the lid, and both arms are attached to the opening. By locking onto the opening frame, the relatively heavy lid plate can stand on its own. On the other hand, since it is necessary to release both arms from the opening frame when closing the lid plate, it has been considered to provide a lever that allows both arms to be operated simultaneously. This lever is installed between both edges of the lid plate in order to operate the arms provided on both sides of the lid plate, so depending on how force is applied during operation, the lever may tilt to the left or right. This may result in the inability to operate both arms in the same way.

The present invention was created in view of the above-mentioned problems, and its purpose is to provide a handle in the center of the lever so that when the handle is operated, the lever can be operated without causing the lever to tilt. The arm can be operated reliably by making it possible to operate the arm, and by providing the handle so that it can rotate around the axis of the lever, the handle can be oriented in a direction that makes it easier to apply force when operating the lever. An object of the present invention is to provide a self-standing device for a lid of a floor opening.

The lid self-standing device for a floor opening according to the present invention includes an opening frame that is attached to the periphery of an opening formed on a floor surface;
A cover plate that can be freely opened and closed between a position where the opening frame is closed and a position where the opening frame is opened by rotating with a rear edge left on the rear edge of the opening frame, and one end of which is attached to both side edges of the cover plate. Each is rotatably mounted around an axis approximately parallel to the opening, and the other end is vertically movable within a through hole formed in each side edge of the opening frame so as to penetrate vertically. A pair of arms are inserted, and both ends are slidable into elongated holes formed along both side edges of the cover plate at a position rearward from the pivot point between the cover plate and the arm at the side edge of the cover plate. It has a lever that comes into contact with the lower edge of the arm when the lid is attached and the lid is open, and a spring that biases the lever toward the front of the lid. is provided with a protruding claw piece that engages with the lower surface of the rear edge of the through hole when the cover plate is pushed forward by a lever biased by a spring means when the cover plate is in the open position. When the plate is in the open position, the claw piece faces the front edge of the hole when it engages with the periphery of the hole, and when the lever is located at the rear end of the slot, it is inserted into the hole. A roughly U-shaped handle is attached to the center of the lever so that it can rotate freely around the lever's axial direction, and a pair of handles are attached to the center of the lever so that it can rotate freely around the lever's axial direction. In addition to providing a lever that allows the arms to be operated simultaneously, by providing a handle in the center of this lever, both arms can be operated equally without tilting the lever by operating the handle against the spring force of the spring means. Furthermore, since the handle is rotatable relative to the lever, it is possible to orient the handle in a direction that is easier to operate depending on the direction in which force is applied to the lever. It is something.

Hereinafter, as an embodiment of the present invention, a device for making the cover plate of an underfloor storage stand independent will be shown. As shown in Figure 1,
An opening 2 is formed in a floor surface 1, and an opening frame 3 is attached along the periphery of the opening. A storage box 14 which is open at the top and whose opening edge matches the opening frame 3 is attached under the floor. As shown in FIG. 2, the opening frame 3 includes a back crosspiece 15 disposed on the back side of the periphery of the opening 2 on the floor surface 1.
It is placed on a frame beam 16 having a substantially L-shaped cross section and fixed to the frame frame 16 . The opening frame 3 is formed to have a substantially L-shaped cross section, and a flange portion 17 is formed at the upper edge of the vertical piece to be secured to the floor surface 1. A through hole 6 is formed in a horizontal piece on the side edge of the opening frame 3, and a through hole 6 is formed to penetrate vertically, and a protrusion 18 is formed at the tip of the horizontal piece of the opening frame 3, projecting upward over the entire circumference. The cover plate 4 rotates with its rear edge remaining on the horizontal piece of the rear edge of the opening frame 3, and the peripheral edge of the cover plate 4 is placed on the horizontal piece of the opening frame 3, thereby closing the opening frame 3. .
One end of an arm 7 is rotatably attached to the side edge of the cover plate 4, and the other end of the arm 7 is inserted into the through hole 6 formed in the opening frame 3 so as to be vertically movable.
A claw piece 5 projects rearward from the other end of the arm 7. The lower edge of the claw piece 5 is arc-shaped, and the upper edge of the claw piece 5 is bent into a substantially U-shape. A reinforcing bar 12 is fixed to the back surface of the cover plate 4 along the left-right direction. Both left and right ends of the lever 10 are inserted into elongated holes 9 formed in the side edges of the cover plate 4, and are slidable within the elongated holes 9. Further, the lever 10 is urged forward of the cover plate 4 by a spring means 11. That is, when the cover plate 4 is opened, the arm 7 moves upward within the through hole 6, and when the cover plate 4 is completely opened, the upper edge of the claw piece 5 is locked to the rear edge of the through hole 6. Ru. At this time, the lever 10 is moved to the front end position of the elongated hole 9 by the spring force of the spring means 11, and the lower edge of the claw piece 5 comes into contact with the front end of the through hole 6. Further, the rear end edge of the cover plate 4 is locked to the protrusion 18 of the opening frame 3. Therefore, even if the cover plate 4 tries to fall backward in the open state, the rear end edge of the cover plate 4 and the protrusion 18 will not engage with each other, and the upper edge of the claw piece 5 and the rear edge of the through hole 6 will not engage with each other. The stop prevents you from falling backwards,
Furthermore, the engagement between the front edge of the claw piece 5 and the front edge of the through hole 6 prevents the cover plate 4 from falling forward, allowing the cover plate 4 to stand on its own in the open state. To close the cover plate 4, move the lever 10 to the rear end position of the elongated hole 9 and move the cover plate 4 forward. The engagement between the claw piece 5 and the periphery of the through hole 6 is released, and the arm 7 is opened through the hole. It becomes possible to move up and down within the hole 6, and the cover plate 4 can be closed. By the way, in order to operate the lever 10 as described above, a handle 13 is attached to the lever 10 at a central position in the left-right direction of the cover plate 4, as shown in FIG. The handle 13 is formed in a substantially U-shape and is attached to be rotatable around the axis of the lever 10, and because the handle 13 is provided at the longitudinal center of the lever 10, , the force applied to the handle 13 is applied equally to both ends of the lever 10. That is, when closing the lid plate 4, the lever 10 is moved to the first position.
It is necessary to push the lever downward in the figure, but at this time, since the handle 13 is provided in the center of the lever 10, the arm 7 is operated almost simultaneously at both ends of the lever 10, and the lever 10 This prevents wobbling and prevents both arms 7 from being operated unevenly. Furthermore, since the handle 13 is rotatable around the longitudinal direction of the lever 10, the handle 13 can be oriented in a direction that makes it easier to apply force to the lever 10 during operation. That is,
When opening the cover plate 4, after opening the cover plate 4, lift the handle 13 onto the lever 10 as shown in FIG.
This allows for secure locking. On the other hand, when closing the cover plate 4, as shown in FIG. 4 can be closed. A reinforcing plate 20 is superposed near the rear of the opening frame 3.

As described above, the present invention has a substantially U-shaped structure in which the arms provided on both sides of the lid plate are attached to the center of the lever, which is operated at both ends in the longitudinal direction, so as to be able to rotate freely around the axial direction of the lever. Since the handle is attached, a lever is provided that can simultaneously operate the pair of arms provided on both sides of the lid plate, and the handle is provided in the center of this lever to resist the spring force of the spring means. When the handle is operated, both arms are operated equally without tilting the lever, and both arms can be released from being locked in the through hole of the opening frame almost simultaneously, and as a result,
It has the advantage of providing a good operational feel. In addition, since the handle is rotatable relative to the lever, the handle can be oriented in a direction that is easy to operate depending on the direction in which force is applied to the lever. This allows you to feel the operation.
